Description
Zoom on the Ryobi RY905500
In summary, the Ryobi RY905500 is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in outdoor fairs, festivals or events
- Food truck owners who want to ensure that their business is fully self-contained and does not rely on potentially unreliable external power
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals who want to be able to deliver results, even during a power failure
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Ryobi RY905500
The Ryobi RY905500's engine, 420 cc Ryobi OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 5,500W and reaches a peak wattage of 6,875W.
The generator features Ryobi's EasyStart pull-start mechanism (more information below). It is rated for a noise of 78 dBA (less noisy than a shower).
With a fuel capacity of 6 gallons, the RY905500 may run for around 10 hours at 50% load with a full tank (fuel consumption around 0.6 GPH).
The powering of sensitive electronic devices with the RY905500 is not recommended due to its high THD (<20%).
Outlets
The control panel features the upcoming 5 AC outlets:
Due to the featured twist-lock L14-30R receptacle, the RY905500 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
Portability
With its dimensions of L31.5 x W29 x H24 in, the conventional, open frame design of the Ryobi RY905500 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
As the generator's weight is 192 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.
EasyStart Mechanism
Ryobi's 3-step EasyStart mechanism
The unit benefits from Ryobi’s EasyStart mechanism. This 3-step starting system allows you to easily start your generator. It works in the following way:
- Put the engine switch on the “ON” position, and place the lever on the “START” position
- Pull the recoil until the engine runs
- Let the engine run 15 to 30 seconds and place the lever on the “RUN” position
Features
The RY905500's control panel
The RY905500 and its control panel include a convenient meter showing you voltage, frequency and lifetime hours. This feature comes handy when monitoring its status and activity.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Ryobi RY905500 also is packed along with the following accessories: tool kit and oil.
Emissions
The Ryobi RY905500 is EPA approved, but NOT CARB-compliant. Thus, it cannot be purchased or sold in California.
However, it features a spark arrestor, so it is adequate for use in forested areas.
Product Video
The Ryobi RY905500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Ryobi RY905500 compare to generators of similar power (between 5000 and 6000 W).
- At a dry weight of 192 pounds, the Ryobi RY905500 is one of the heavier devices which can produce between 5000 and 6000 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Genmax GM6000XiE, with a dry weight of just 106.9 pounds.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 78 dBA can be judged as noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Honda EU7000iS, whose lowest noise levels reach just 52 dBA.
- As for its autonomy, the RY905500, with an autonomy of around 10 hours at a 50% load, is placed on the low end among the generators of its kind. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Cat RP5500, with around 15 hours.
- Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.6 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA7000L. With a fuel consumption of as little as 0.36 GPH, it is one of the most efficient generators currently on the market.
The bottom line
- Several accessories included
- GFCI Outlets
- No electric start
- Not CARB-compliant
- On the heavy side (192 lbs)
- On the noisy side (78 dBA)
- Relatively low run time
- Low fuel efficiency
